The Best (and Worst!) Nail, Hair & Makeup Trends of 2010

You loved them or left them, either way you definitely noticed them -- here are the beauty and makeup trends we cherished and loathed

Trends, be it fashion or beauty, are hard to navigate. Some that are awe-inspiring on the runway or red carpet look downright ridiculous strutting down the aisles of Costco. Case in point: Ke$ha looked like a bad-a$$ in blue lipstick, but if we tried to wear it to work, the boss might ask to "have a word" with us.

Before you accuse us of being too judgmental or close-minded, know that we believe all trends, good and bad, to be necessary. We need some less-than-hip transients to remind us of how important classic trends are like red lipstick. And not to say we have never fallen victim to "bad" trends before, heck, we wore scrunchies in public back in the day, too. You see, we need makeup, nail and hairstyle trends, no matter how embarrassing, in order to differentiate between the classics that deserve more than just their fifteen minutes. However, the real stars are the good trends that reinvigorate our love for beauty -- that is, until the next hot new thing shimmies on by.

And because it is sometimes difficult to separate the looks we should commit to from the ones we should only flirt with, we thought we'd share our opinions on what should stay and what should go. We've rounded up the most popular hairstyles, makeup looks, and nail trends from the past year in order to help you navigate which trends to keep and which to ditch come January 1st. So, you can take our word for it or be the last person wearing hair tinsel at the PTA meeting … you decide.

I'm sorry but I really hate the ballerina buns. I don't know why they are so popular when they seem to make even stunningly beautiful women look like the cast of Star Trek. There is a reason these buns are worn ON-STAGE. This style was horrible in the 80's (for those of us who lived through them) and it is even worse now.
